Mechanism to allow Servo to prompt the user

This blocks the embedder thread (compositor thread). Not ideal. I don't think it's too much work to only block script, I'll do that in a follow up bug.

Fix #23376

@Manishearth we have a few new APIs. Hopefully this will cover your needs. A thing I haven't implemented yet is a way to ask the user to pick from a list. Let me know if it's something you'll need.
